E. MENDOZA ET AL TAKEUP DEVICE FOR LOOMS Filed Feb. 15, 1951 INVENTORS ATTORNEY Patented Feb. 2, 1932 STATE-S ERNESTO MENDOZA AND RAMON SALA, on. MEXICO, MEXICO TAKE UP DEVICE FOR LooMs Application filed February 13, 1931. Serial No. 515,609.

This invention relates to improvements in looms and has particular relation to means for taking up the cloth during the operation of weaving.

Another object of the. invention is the provision of means of the above character which may be accurately adjusted in accordance with the number of picks of the loom, so that imperfect places in the weave will be avoided.

With the above and other objects in view, the invention further includes thefollowing novel features and details of construction, to be hereinafter more fully described, illus- 1 trated in the accompanying drawings and pointed out in the appended claim.

Tn the drawings Figure 1 is a view partly in end elevation and partly in section illustrating the invention.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Referring to the drawmgs in detail wherein like characters of reference denote corresponding parts, the reference character 8 indicates the winding roll of the loom, while the reference character 1 indicates the driving shaft.

Keyed upon the winding roll 8 is a sleeve 17. The inner end of this sleeve rests against a shoulder provided at the end of thewinding roll and is provided at this point with,

a beveled flange 7. Mounted upon this sleeve 17 is a collar 15 which forms one member of a clutch mechanism to be later described. This collar is provided with a recess to receive the flange 7 and is forced upon said flange and locked to the sleeve through the medium of a nut 9 which is provided with an operating arm or handle 10. The sleeve 17 is held against axial movement by means of a nut 19 which is threaded upon the end of the winding roll 8 and which is provided with a crank handle 20.

The collar 15 is provided with a plurality of spaced recesses 18 in its periphery, the said recesses having inclined bottom walls. These recesses are closed by means of rings 3 and 14, the said rings forming the outer walls of 50 the recesses so as to provide tapered pockets V and takes up lost motion when the ring be-.

for the accommodation of rollers 5. Two rollers are provided 'in each of: the pockets and are arranged end to end, so that one roller will engage the inner periphery of the ring 3 and the other roller the inner periphery of the ring :14. These rollers are held in place by means of rings 6 which threadedly engage the collar 15 and which are provided with sockets '11 for the reception of asuitable tool. I

Extending from the ring let is an arm lt, .60

see Figures 1 and 2, andthis arm is adapted to be suitably fixed to the stretching table or other convenient part of the 100111 (not shown). I q 7 Extending radially from the ring 3 is a 65 threaded arm 13 and threadedly mounted upon this arm is an int'e'riorly and exteriorly threaded sleeve 2. Threadedly engaged upon the sleeve 2 is a clip 12 and pivotally mounted between the ends of this clip as 7 shown at 12' is one end of a rod or arm 21. The other end of this arm'is threadedly en-' gaged with an eccentric strap 22 which, sur rounds an eccentric mounted upon the drive shaft 1 and which causes the rod 21 to reciprocate as the shaft 1 rotates.

It will be seen from the foregoing description and accompanying drawings that operation of the shaft 1 will impart an oscillatory movement to the ring 3, the degree of which is governed by the position of the clip 12 upon the sleeve 2, the position being regulated by the number of picks of the cloth. Movement of the ring 3 in a clockwise direch tion will lock this ring to the collar 15 and will thus impart alike movement to the collar, and as this collar is locked to the winding roll 8, the latter will be likewise moved. Movement in a reverse or anti-clockwise dim rection will permit the ring 3 to run free, so that no movement of the collar 15 will occur. The ring 14 will hold the roll 8 against retrograde movement- Each of the recesses or pockets 18 is provided at one end with a cushioning plunger 4 against which the rolls 5 engage when the ring 3 is moving in an anti-clockwise direction. This permits free rotation of the collar gins its movement in an anti-clockwise direction.

The sleeve 2 and arm 13 are provided with transverse openings for the reception of a sealing wire 24 so as to prevent tampering with the adjustment of the device. The outer end of the sleeve 2 is provided witha cap or collar 23 which is secured to the arm '13 by means of a screw.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right isherein reserved to make such changes as proper- 1y fall within the scope of the appended claim.

Having described the invention what is claimed is In a take up mechanism for looms, a clutch mounted upon the winding roll of the loom to impart a step by step rotation thereto and including a ring member having aradiallydisposed arm, a sleeve journalled upon said arm and having an external thread means for fix-- ingthe sleeve with relationto the arm, a clip threaded upon the sleeve and-a rod pivotally -connected with the clip and adapted to be operatively connected with the shaft of the loom.

In testimony whereof we afiiX Our signatures.
